This invention relates to a conveyor system :for handling objects suchas packing cases, and relates more particularly to an improved conveyorsystem Iprovided with a movable, tiltable section whereby packing casesriding along the conveyor system may be tilted out of line to facilitatethe loading thereof.

An object of this invention is toy provide a tilting section in apacking case conveyor system adapted to shift a packing case restingthereon out of the main conveyor line and simultaneously to tilt thecase and to render the bottom-most section of the case on the tiltedsection of the conveyor system more easily accessible for proper packingthereof.

Another object of this invention is the provision of tilting means in asection of a conveyor system adapted to tilt an Object, such as apacking case, riding thereon to the desired angle and to lock said casein tilted position automatically in a single operation.

Other objects of this invention will appear from the following detaileddescription and the accompanying drawings.

In the drawings,

Fig. l is a side elevational view of the novel tilting section of myinvention having a packing case thereon, showing mechanism for drawing'8 Claims. (C1. 22S-'129) the section out of line and simultaneouslytilting it, and

Fig. 2 is a front elevational view of a conveyor line having the noveltilting section of my invention in combination therewith showing thehandle whereby the tilting section and the case thereon may be drawnfrom the main conveyor line and placed in tilted position.

Like reference numerals indicate like parts throughout both `views ofthe drawings,

Referring now to the drawings, and more particularly to Fig. 2, the mainpacking case conveyor line employed in connection with my novel tiltingsection comprises, in its several parts, stationary sections 3, onlyportions of which are shown, together with a short stationary section 4intermediate thereof in the gap formed by the removal of the tiltingsection. Thusthe novel tilting section of my invention, generallyindicated by reference numeral 5, is so positioned that the frameworkthereof straddles stationary section 4. The construction and operationof said tilting conveyor section is hereinafter described. Stationarysections 3 and 4 are provided with a plurality of cylindrical rollers B,which rollers are rotatably mounted in horizontal supporting members 'Iand 8, respectively. The several supporting members 'I are set on posts8 anchored to the flooring by suitable means (not shown). Supportingmember 8 of the central or stationary section 4 is set on posts I0 fixedto the flooring by bolts II. The stationary sections 3 and 4 of theconveyor system are capable of carrying any heavy object such as apacking case, for example, the latter being indicated by referencenumeral I2. Packing case I2 may be moved along the conveyor lineindependent of tilting conveyor section 5, it being large enough tobridge the gap formed when the tilting section is removed from theconveyor system.

The tilting conveyor section 5 of my invention comprises a frameworkconsisting, in its several parts, of a pair of horizontal rectangularstructural members I3 having a plurality of cylindrical'rollers I4rotatably mounted therein, and a U-shaped channel member I5 set beneathand attached to members I3 to provide additional rigidity and strength.vChannel member I5 is connected to rectangular members I3 through thebrackets I6 mounted on channel I5 by means of bolts I1. Brackets It arenivo-tally linked to a second pair of brackets I8 through pins I9,brackets I8 being fixed to members I3 by means of bolts 20.

The entire tilting conveyor section 5 rides out of the main conveyorline consisting oi' stationary sections 3 and 4, on a plurality ofcasters 2l. Casters 2I are attached to the lower side of channel I5 inany suitable manner and are provided with grooved wheels 22 set ontracks 23 which are anchored to the flooring by bolts 24.

To effect the desired tilting action in conveyor section 5, when thelatter is drawn out of the main conveyor line, there is provided aninclined stationary trackway which consists of a pair of guide rails 25mounted on posts 26 and 2l. 'The latter are anchored to the flooring bybolts 2B and 29 which pass throughv angle irons 3|) and 3|,respectively. Posts 2@ and 27 are welded to said angle irons and thelatter serve to give the posts greater strength and rigidity. Guiderails 25 which comprise the inclined trackway each contains a roller 32rotatably mounted on a short shaft 33. Shafts 33 are attached todependent legs 34 welded to angle irons 35 which, in turn, are welded tothe lower side of rectangular members I3. l

In order to draw the conveyor section 5 outof the main conveyor line andto effect the tilting of packing case I2, when the latter is in posiltion on said tiltingconveyor section 5, as shown in Fig. 2, the operatorgrasps the handle 36 atcase I2 is in the position I2' shown in dot-dashvlines in Fig. 1 and comes to rest on a brake ory stop member 31 pivotedon post 31. Stop member 3'! and post 3l are not shown in Fig. 2 for thesake of clarity. The upper surface of stop member 3'! is covered withrubber to prevent packing case I2 from moving, laterally of the tiltingsection, on rollers I4. As the conveyor section is tilted as far as itwill go, it is simultaneously locked into tilted position by theactionof atrigger. 38 which hooks under a catch 3 9." Inl position I2the packing case may be packed efficiently since the bottom thereof vis,within easy reach.

'j AAfter case.I2 has been packed and is to be returned to the mainconveyor line, the operator forces lever 40 toward handle 36 whichcauses rod 4I to move upward. This action draws trigger 3B. from catch39 since the upward movement of rod 4I causes trigger 38 to pivot inbracket 42 in.which said trigger 38 is mounted, and to be thus released.The downward pull exerted by the weight of loaded case I2 together witha slight Ipush ori-handle 36 by the operator after trigger 38isreleased, rolls the tilting conveyor section 5 backinto the mainconveyor line. When both thestationary and tilting conveyor sections arein normal running position, rollers I4 are lined upvwith rollers 5 ofthemain conveyor. While .rollers 1 I4 may be on the same level as rollers6, as shown in Fig. 2, rollers I4 are preferably set .slightly higherthan rollers 6 so that the loaded packing case I2 may again be startedalong vthe main'conveyor line with as little effort as possible.

;;. Itis to be understood that the foregoing detailed description isgiven merely by way of -illustration and that many variations may bemade thereinwithout departing from the spirit of my invention.
